I love Bradbury's voice and his flair for excellent stories. This book of essays (or intros or interviews) is a bit of a grab bag - some bits made me nostalgic in the best of ways, some bits genuinely inspired me, and some bits I was annoyed that he enjoys writing this much when it's so tough for the rest of us.
I wouldnt recommend it if you haven't at least read f451 and martian chronicles.
